Starting a dummy instrument from the serverConfig.yml throws error

[rroodll]

This deosn't seem to effect usage, just seems to be a weird error that I only see starting from the serverConfig.yml. When I try and connect to the dummy instrument directly it does not throw this error in the InstrumentServer log.

Is the below error simply a mis-configuration? (see bottom for config file entry)
